Finally, 25SiMn2MoV offers a high degree of resistance to wear that is unmatchable with regular steel. As it is a very strong alloy steel, components made from 25SiMn2MoV are exceptionally durable and can withstand wear and tear better than other steel alloys. This feature makes it ideal for use in components that require a high degree of wear resistance such as oil and gas equipment, earthmoving machinery and tractors.

Overall, 25SiMn2MoV is an impressive alloy structural steel that offers excellent strength and machinability, weldability and wear resistance. Its strength and formability makes it ideal for the manufacture of large industrial machines and its corrosion resistance makes it suitable for a variety of applications. With its many advantageous properties, 25SiMn2MoV is essential for a range of industries and products.

25SiMn2MoV alloy structural steel is a kind of low alloy structural steel with excellent comprehensive mechanical properties and excellent hardenability. Its mechanical properties and hardenability are much higher than those of pure carbon structural steels. Its hardenability is nearly equivalent to some of the alloy steels and its quenching degree is higher than that of 40CrNiMoA.

The chemical composition of 25SiMn2MoV alloy structural steel is as follows: C: 0.15-0.25, Si: 1.60-2.20, Mn: 2.30-2.70, Mo: 0.20-0.50, V: 0.15-0.30.

25SiMn2MoV alloy structural steel has lower hardenability than AISI/SAE 4340 alloy steel, but higher quenching hardness and higher fatigue strength than AISI/SAE 4140. Its tempering temperature should not exceed 540℃, otherwise its strength and toughness will be greatly reduced.

25SiMn2MoV alloy structural steels are used for the manufacture of important parts and components in the automotive industry, machine tool industry, and other high-end industries with higher requirements on the mechanical properties and hardenability of the material. Typical applications include crankshafts, axle shafts, connecting rods, fasteners and transmissions in automobiles and construction vehicles.

25SiMn2MoV alloy structural steel is characterized by high hardenability, good overall mechanical properties, but poor thermal strength and poor machinability. Therefore, when cutting and processing, the tools and tool holders should be selected according to the characteristics of the materials.

In summary, 25SiMn2MoV alloy structural steel not only has good comprehensive mechanical properties, but also has good hardenability, so it is an ideal material to make important parts and components in the automotive industry and machine tool industry.
